IMPACT WATER-M oToR.

Y SPECIFICATION forming part of Letters Patent No. 682,664, dated September 17, 1901.

Application filed May 15, 1961.

To @ZZ whom t 19e/ty concern:

Be it known that we, WILLIAM BOEKEL and JULIUs BOEKEL, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Impact Water-Motors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to impact Water-motors the casings of which are made up of sep- -arable sections; and it consists in the construction and combination of parts hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure l represents a vertical central section through 'a motor embodying our invention. Fig. 2 represents a perspective view taken from above from the bottom section of the casing detached. Fig. 3 represents a similar view Aof 4the middle section of the casing. Fig. 4 represents a similar view taken from below of the Itop casing of the section. Fig. 5 represents a horizontal section through the mo- 4tor on the line of the semicircular waterway Fig.. -6 .represents a detail view of the wheel and its spindle.. y

A designates the annular section of the casing, having cast with its inner surface a semiifrom the outside of the casing through an inlet D, protruding tangentially therefrom and externally screw-threaded to receive a coupling E, whereby the end or nozzle e of a pipe or hose (indicated by dotted lines) is attached. The said waterway is provided with a jethole d in line with the bore of said inlet; also, with another jet-hole c, diametrically opposite thereto, the water issuing from these jetholes being directed against and into concave peripheral cups or buckets f of a wheel F, which carries a spindle G, said wheel and spindle being connected by a pin g, which passes through a hole in the upwardly-projecting hub F' of the said wheel and into a recess of the said spindle. The said spindle may carry tubes or vessels arranged to be tested by centrifugal action or any other convenient devices. The said wheel is supported Serial No. 60,350. (No model.)

by a bearing-sleeve t', raised on thetop of a broad flat U-shaped bridge Lwhich is cast or otherwise made rigid and practically integral with the cover J of the casing. The spindle aforesaid is stepped into this bearingsleeve, a downward extension t" of which is provided below the said bridge with internal screw-threads receiving a small screw-plug j, which confines lubricating material Within the 6o bore of said sleeve, but allows at will access to said bore and the lower end of said spindle. A long guide-sleeve K is raised centrally on the said top J, being connected detachably thereto by internalscrew-threads on the lower end of said sleeve engaging a screw-threaded stud, the said sleeve serving to guide, brace, l and protect. the spindle aforesaid. The construction of these parts at the upper end of the motor has the advantage of keeping the 7o bearings of the wheel and spindle all together in the top plate J and bridge I, which are actually or practically one piece. There is consequently no risk of the bearings getting out of line, so as to cause wear and strain, nor any need of special care or expediente to avoid such a defect. Moreover, the wheel and spindle and all proximate parts are very easily removable as one piece to allow-inspection, cleaning, and repair.

The cover J is fastened to the middle section A by screws L, which pass through holes in said cover into screw-tapped internal lugs or blocks L inside of section A and cast therewith.

The bottom section M of the motor is provided with legs or supports fm and with an -outlet O in the form of a trough extending radially from its center and discharging at its side through a short tubular neck O', to 9o which a pipe may be attached. An outlet at the bottom of a motor tends to create a vortex which would prevent the free escape of water and impede more or less the action ofthe wheel. To guard against this, we provide two raised flanges P and Q, extending each half-way the top of said bottom section M, so

as to leave the central part of said plate, including, the beginning of the said outlet, between them. The top of said section or plate roo M is concave, the center being its lowest point. The water descending from the wheel is prevented by these flanges from making the circuit of the said plate and is directed straight into the said outlet without forming a vortex.

Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. In an impact water-motor, the combination of a water-wheel and its spindle with the top section of the casing by which they are carried and with which they are removable, the middle section of the casing being provided with a Waterway and nozzles for impact jets and the bottom section with an outlet substantially as set forth.

2. In an impact water-motor the combination of a water-wheel and its `spindle with a casing in three detachable sections, the top section being provided with bearings for the said spindle and wheel which are removable with it, the bottom section being provided with an outlet and the middle section being provided with a waterway which discharges through nozzles against the periphery of said wheel, substantially as set forth.

3. ln awater-Lnotor a casing having a bottom section or plate which is concave on top to a central opening discharging out through its side, the said plate or section being also provided with two raised anges which eX- tend inwardly from opposite sides of the said plate on parallel lines, leaving the beginning of the outlet between their inner ends and serving to prevent a vortex substantially as set forth.

ln testimony whereof We affix our signatures in presence of two witnesses.
